Business Contact Manager - Accounts, Sending Emails

[huxtabl]

When attempting to use a Business Account as the means for sending an email message to ALL the business contacts loaded into that account, I get an error message saying the account requires a valid email address -- despite the fact that all the contacts have valid email addresses. Outlook/Business Contact Manager apparently wants a single email address for the account -- which would limit me to sending a message to only one person at the account. To do this, I'm opening the account, and then selecting Actions -> Create New Message. Is there a "right" way to do this? The Help Topics do not cover it. Thanks.
